Abstract
The invention provides a special anticorrosive paint for sucker rods, which is prepared from the following components in percentage by weight: 45-50% of solid asphalt, 12-20% of asphalt softening agent, 1-1.5% of preservative, 5-10% of 200# solvent oil, 10-155 of aromatic solvent and 10-15% of xylene. The invention also provides a preparation method of the special anticorrosive paint for sucker rods. The melting point of the anticorrosive paint for sucker rods is 70-80 DEG C, and thus, the paint can not be molten if meeting with hot weather in the transportation process; and the paint film can not shed from the coated object, and thus, can perform favorable anticorrosive function. In the working process of the sucker rod, the temperature of the sucker rod increases as the sucker rod rotates, and the anticorrosive paint with the melting point of 70-80 DEG C can automatically melt as the equipment operates, thereby further enhancing the production and product quality.
Description
Technical field
The present invention relates to protective system technical field, particularly a kind of sucker rod special anti-corrosion paint and preparation method thereof.
Background technology
Sucker rod is the slender rod piece of rod-pumped well, connects polished rod on it, under connect oil pumping and pump up the effect of transferring power.Sucker rod joint length is 7.6 or 8 meters, material is generally high carbon steel plating hard chromium on surface, in oil pipe, with internal thread hoop, couple together one by one and extend on the piston at oilbearing stratum place always, by to-and-fro movement, carry out pump oil, current oil well length is generally in two km left and right.Because the storing time is longer, storing condition is poor again, while causing on many sucker rods well, has got rusty, the even appearance erosion point and the pit that have.This non-uniform corrosion of bar, makes it at when work stress concentration and cause fracture often, and what impact was recovered the oil normally carries out.
Existing pumping rod anti-corrosive paint, when temperature reaches 40～50 ℃ while spending, will melt.Sucker rod installs after paint in painting, runs into hot weather in transportation, and paint will melt, and paint film departs from coated article part, does not reach rot-resistant effect.Also have some antifouling paste fusing points very high, can cause product when in use, paint film can, along with equipment operation automatic dissolving, not produced and quality product thereby affect.
Summary of the invention
The technical problem that the present invention solves is to overcome the above-mentioned deficiency in prior art, provides a kind of and when transportation, is difficult for fusing and holds in use caducous pumping rod anti-corrosive paint having and preparation method thereof.
Technical scheme of the present invention is achieved in that a kind of sucker rod special anti-corrosion paint, is made: solid bitumen 45～50%, pitch tenderizer 12～20%, sanitas 1～1.5%, 200 ﹟ solvent oils 5～10%, aromatic solvent 10～15% and dimethylbenzene 10～15% by the component of following weight per-cent.
Wherein, preferably, described solid bitumen softening temperature is 110～120 ℃, flash-point >=260 ℃, ash content≤0.3%.
Wherein, preferably, described pitch tenderizer is through underpressure distillation and solvent pairs extracting and make aromatic hydrocarbon content >=80% by the recycle stock of crude oil gained after catalytic cracking or slurry oil.
Wherein, preferably, described aromatic solvent is that boiling range is the aromatic solvent of the low boiling range of 155～175 ℃.
A preparation method for antifouling paste for sucker rod patent, comprises the following steps:
1) solid bitumen is dropped in still and be slowly heated to dissolve, be then cooled to 140～160 ℃;
2) add 200 ﹟ solvent oils to be stirred to completely and dissolve in, then add aromatic solvent and dimethylbenzene, stir evenly;
3) cooling, when temperature is down to below 50 ℃, then adds pitch tenderizer and sanitas, after stirring evenly and get final product.
The present invention has following beneficial effect:
1. pumping rod anti-corrosive urushoil fusing point of the present invention is at 70～90 ℃, and the pumping rod anti-corrosive paint of this fusing point is in transportation as run into hot weather, and paint will not melt, and paint film can not depart from coated article part, the preservative activity that can play.In sucker rod work, along with the rotation sucker rod temperature rising of sucker rod, the pumping rod anti-corrosive paint of this fusing point can, along with equipment operation automatic dissolving, further improve and produce and quality product.
2. pumping rod anti-corrosive paint of the present invention has very strong airtight and watertightness, and cost performance is high, can significantly reduce production costs.
